Referring to the drawings, the machine illustrated therein, which, withexceptionsV to be noted below, is similar to the machine illustratedinapplication Serial No. 593,981, referred to above, has a friction rollfor tensioning andoverdrawing the stock the lasting margin of` whichisyieldingly pressed against an operatingsurf-ace II'of the roll, at twolocations spaced circumferentially thereof, by means of a pressuremember `com-prising a body portion I2 and a hinged part@ I4; 'a wiper,indicated by the'reference character I6; an edge gage roll I8; and ashoe-bottom rest 20.

The roll I0 is mounted on the lower end of a shaft 30 which is journaledin a bearing block 32. This block has a T-shaped arcuate rib 34 which isslidably mounted in a correspondingly shaped groove 35 formed in asupporting bracket 36, Figs.i

2 and 4. The bracket 36 is likewise providedwith a T-shaped arcuate rib38 that is slidably mounted in a correspondingly shaped groove 40 inl aplate 42. As is explained'in detail in the above-A mentionedapplication, these arcuate'groov'es and ribs are so arranged asytoj'perrriit the varying'of -the inclination of the shaft 30,- togetherwith the roll I0, without altering the vertical position of the roll,and clamping boltsl 43 and 44 are provided f-or locking the bearingblock 32 and bracket 36, respectively, after the roll has been adjusted.The plate 42 is secured to`a'slide`45 by means `o`f`a tongue 46 andgroove 48 and clamping bolts -50 which pass through elongated slotsinthe plate, see Fig. 2. When these bolts'are loosened the roll may beadjusted tow-ardor awayfroml the wiper |6.

The slide 45 `is supported in .a guide bracket 52 which is secured to aframe member 54. that is mounted on the top of a column 56 ofsuitableheight, Fig. 1. A cam roll 5B, carried bythe slide 45, runs ina camgroove 60 formed' ina cam bar 62 which is mounted for vertical slidingmovement 4 cal shaft 86 that is journaled in bearings 88 and 60 in .agear housing 12 carried by the frame 54. The gear 82 drives, through -areduction train comprising gears 92, 94 and 96, a shaft 98 that isl.likewise journaled in the housing 12 and which projects through itslower W-all. rThis shaft is connected to, the shaft 30, `which carriesthe roll I0, r'ine/an'sg-,off'an extensibleshaft assembly inv'dicatedbythe reference character |00 and includ- ,ing universal joints |02 and|04. A sheet-metal Aguard housing |06 surrounds the extensible shaftfl'gas shown in Fig. 1.

The body portion I2 of the pressure member is secured; bymeans of a boltI0, to the lower end of'an 'arm ||2 which is pivotally mounted on thebearings block 32 by means of a pin ||4 that exl. tendsthrough/flanges||6 in the bearing block,

see Fig. 2. The bolt ||0 extends through lan elongated slot I I8 in .thebody portion of the presswing in a c-ounterclockwise direction, and.toward sure member,v Fig. 3, which, when the bolt is loosened, permitsadjustment of the pressure `memberlaterally ofthe machine and relativelyto the roll' I0.v The hinged part I4 of the pressure member ispivotallymounted on the body portion I2 by means of a pin' |20 and is yieldinglyurged to the roll| 0, about the pin I 20, Fig. 3, by means of acompression spring |22 which is fitted in recesses |24 and I 26 in thebody portion and hinged part, respectively.` A rod |30 having aspherical end |32 is connected to the arm I I2 by aplate |34 and screw|36. This rod extends rearwardly of the machine from the arm I I2 andpasses through an aperture |38 in a bracket member |40 that is securedto the frame member 54. Interposed between a collar |44, adjustablysecured to the rod |30 by a set'screw |46 and the bracket |40, is acompression spring |48.

When the treadle, notV shown, is depressed, the

f-cambar 62 will be moveddownwardly, Aand the in the bracket by means 0fa treadle, not shown,

but connected thereto by :a treadle rod`64. Such' vertical movement ofthe cam Ibar 62,wll shift the bearing block 36 and roll |0 forwardlyorrearwardly of the machine for a purposel Whichwlll presently appear. i

The shaft 3u, 'and m11 lo, are driven noma suitable sourceof pcwer,`notshown, thr'ughfa main input gear |8 which meshes with any idler gear 16,Fig. 1.

The wiper It., which; is. ofnoveland improved construction, comprises arelatively thin disk which is` secured, by means; of screws |80, to `theendl ofa shaft,A |82 that is` journaledrin a bearing block;` L84 andwhichA carries a` beltl pulley |86. 'Ehe `bearing block IBA isadjustably mounted; by means, of boltsv|8=1f and slots |88, on the lowerend of, a `housing |80 that is mounted for angular adjustment about aboss 1| 92 on the lower end ot the housing .12, this boss being centeredabout theiaxis ofshaft 86, and clamping bolts |84 `are provided.`foi-"holding the housing andl wiper disk in adjustedt position. Theshaft 86 carries a beitelfgear |93? which meshes with a bevel gear |94.mounted: on "a countershaft |96.` Also mounted on the shaftl ISE is apulley |98 and a be1t280; runs. over this pulley, the pulley |88 and an.adjustable idler pulley 282. j

The; edge gage roll I8- is Journaled on a stud 21|I which is carried byal block2| 2 that is mounted fonadiustment; forwardly and rearwardly of``the machine, `on an arm 2|8 by means of a clamping bolt 2|6` whichpasses through a slot 2|4 in the block, Figs. 2g 3 and 5. `The arm 2|8is likewise mounted for adjustment,` laterally of the ina.- chlnetbi1-means ora clamping bolt 222 and slot Mumia bar12-24 and this bar ismounted for adjustment `vertically of the machine on a slide 238'; bymeans ofabolt 232and` a slot 234. The

slide 236i i`s`1 mounted for reciprocating movement in a"`gui`cleIbracket, notshown, but similarfto 1the bracket 52 and secured to theframe 54. This slideis moved forwardly and rearwardly of .the machine bythe cam bar-v62 when the treadle is operated in theA same manner asslide 42, as is explained in detail in the abovemennoned application,Serial No. 593,981.

The bottoni rest is mounted on the bearing block32, for angularadjustment about the; axis ofthe rolll, by means of an arcuate boss 1240on the hearing blockand' a bolt 242 which passes through a slot 244-formed inthe upper end of the bottom-resnsee Fig. 1. Y

The operating surface of the wiper l'is formed by? a plurality offcircumferentially disposed. axially offset, helical ribs 308: Theleading ends of these ribs are rounded`,`as indicated at 302, Fig, 5,andeach leadingend is substantially in axial alinement with the trailingend' 34of the next preceding rib so that a circumferentially` continuouswiping surface` is presented to the work, see Figs. 3 and 5, and one ofthe ribs isv always in contact with the work. The effector theroulidedleading ends 302 as, theystrikethe lasting margin is to produce ahammer-likehiow which greatly augmente the action of the wiper incausing adherence ofthe stock to the shoe-bottom member.

However, by arranging the leading ends and `traillng endsof the ribs in`axiallalinement, asabove pointed out, any tendency for the rounded`leading ends to strike` and break downthe edge of the shot-bottommember, herein illustrated as a platform. P, is avoided. The roundedleading ends are formed as continuations` of semicircular recesses 306formedin the side facefofl the disk.

In the manufacture of certain types of platform shoesthe platform coversare madefrom'strip material the lasting margin of whichis ycoated withadhesive in a non-tacky condition;also,the adhesive whichV has beenapplied to the'` platform cover or other stock to be lasted maypn somecases, be permitted to dry for too long a period so that the adhesivereaches .a non-tacky condition in which it will vnot adheresatisfactorilyy if at all, to the shoe bottom member upon being wiped inand pressed down by the Wiper. It has been `found that by applying heatto the `lasting margin of stock of this type during the lastingoperation the adhesive may be lrendered tacky and a satisfactory lastingjob accomplished. I For thus applying heat to the stock, intheconstruction shown in Fig. 4, the illustrated machineis prlovidedwith an electrical heating unit'v 150B, which may be a conventionalplug-type heatingunit, that is press-fitted into a bore 502 in the bodyportion I2 of the Vpressure member.I `From this heating unit leads 504and 5ll61extend to a suitable source of electrical energy,.not shown.During the operation of the machine in lasting the stock, sufficientheat from the portion I2, that is heated by the unit 5|.'III'` and whichpresses the lasting margin M againsttheroll I0,wil1ipene trate throughthe stock and render tacky, i. e.,

activate, the adhesive coating on the inside face thereof.l The degreeof heating of .the body portion I2 will be only sufncient to activatethe adhesive and not enough to scorch or otherwise mar the outside faceof the lasting marginof vthe stock and any suitable form ofthermostaticcontrol may` be used properly to regulate the action of theheating unit 500. While the heatingv unit is herein illustrated asapplied to the modified construction of pressure member vin whichlv thehinged part I4 has been omitted, it will, of course, be readilyunderstood Athat a similar heating ar-` rangement may be provided in thepressure membersshown in Figs. 2 and 3 and which arel provided with thehinged portionv I4. u

The action of the rotary wiper I6 in -laying the overlasted stocksmoothly down on the shoe bottom may be improved by heating the wiper.This may be conveniently accomplished inthe man-` ner shown in Fig. 4 inwhich a block 5I0'having a flat side face 5I2 and provided with anelecrical heating unit 5I4 is adjustably mounted on the bracket 36,bymeans of a support 5I6, bolt 5I8`ands1ot 52D, ear 522, and a clampingbolt 524, so that the side face 5I2 may be"positioned close to the sideface of the wiper.v This heating unit, which is connectedtoa`suitablesource of electrical energy, not shown, by means ofl leads 526and.52, rwill radiate `sufiicientheat tothe closely adjacent wiper tokeep thewiper-itself warmed to a point Wherethe helical ribs 300 willhave a heated ironing action on the over# lasted stock which is quiteeffective in lsr'noothin'g the stock and removing wrinkles therefrom.v
